Royal Mencap Society v Tomlinson‑Blake [2021] UKSC 8
This case confirms that a volunteer with no contractual obligation to perform work is not a worker under the Employment Rights Act 1996. The absence of mutuality of obligation and the purely voluntary nature of the arrangement were decisive.
Overview
This case sits at the intersection of care work, low‑paid labour, and the legal architecture that distinguishes work from service. It is a reminder that the law’s categories—worker, employee, volunteer—are not moral judgments but contractual ones. The courts were asked to decide whether a volunteer who attended a callout, despite having no obligation to do so, could be treated as a worker and therefore entitled to statutory rights.
The answer, delivered with the cool precision of appellate reasoning, was no. The absence of mutuality of obligation—no duty to attend, no duty to offer work—meant the relationship never crossed the threshold into worker status.
Facts
Mr Groom volunteered with the Croydon Relief Organisation (CRO), assisting vulnerable service users and occasionally attending callouts. The CRO handbook set expectations of professionalism and attendance, but crucially, it did not bind him contractually. He received reimbursement of travel expenses only—no wages, no honorarium, no retainer.
In 2016 he attended a callout and later claimed he was a worker under the Employment Rights Act 1996, seeking unpaid wages and holiday pay. The Supreme Court, drawing on the principles articulated in Uber BV v Aslam, emphasised that worker status requires:
• Personal service, and
• Mutuality of obligation—the employer must be obliged to offer work, and the individual obliged to perform it.
Neither existed here. The handbook was not a contract, and the reimbursement of expenses did not create legal obligations. lawcases.net
Judgment
The Supreme Court held that Mr Groom was not a worker. The Court of Appeal’s rejection of his claim was upheld. The reasoning aligned with the broader jurisprudence: voluntarism, without contractual underpinning, does not morph into employment merely because the volunteer behaves responsibly or attends when asked.
The Court reaffirmed that:
• A volunteer’s attendance, even if regular or reliable, does not create mutuality of obligation.
• Reimbursement of expenses is not remuneration.
• A handbook expressing expectations does not constitute a binding contract.
This approach mirrors the logic in Uber BV v Aslam, where the Supreme Court stressed that worker status is grounded in the reality of contractual obligations, not the appearance of structured activity.
Comment
There is a quiet melancholy to cases like this. They expose the gap between the moral value of care and the legal value of labour. Mr Groom stepped forward to help someone in distress—a gesture of civic solidarity. Yet the law, with its insistence on contractual formality, treats that gesture as outside the sphere of employment protection.
This is not a failure of compassion but a structural choice: employment rights attach to obligations, not goodwill. The courts are wary of expanding worker status in ways that might chill voluntary organisations or blur the line between paid and unpaid service.
Still, the case invites a broader reflection. In sectors where volunteers perform roles indistinguishable from paid staff, the boundary between altruism and labour becomes ethically fraught. The law resolves the question by looking for mutuality of obligation. Society may wish for something more generous.
